Since a couple of days I notice smoke/steam coming from under the hood.
Figured it's just a leaking radiator but tonight I had a better look and it seems it's coming from the exhaust manifold area.
Problem is I can't really see where it's coming from exactly.
Had the car on the lift and ruled the turbo side out, the water banjo bolts are dry, but there's coolant on the cold side.
When I tried to find the leak with a small mirror (between exhaust runners 1 &2) the mirror gets fogged right away so can't have a good look. Directly explains the coolant hanging off the turbo cold side; just vapour getting it wet I guess.
Also holding the mirror between the exhaust runners 1 & 2 seemed to block the vapour going towards the turbo.
So it seems it's coming from either a leaking exhaust gasket but it doesn't sound like that. Also it would need the water to get into the exhaust port in the head in the first place, but there is a lot of vapour coming out of the back of the exhaust as well.
It (the vapour) also seems to be coming out under pressure, not just leaking on the manifold, but I can't feel where it's coming from cause I can't get my hand in there.
On the other hand it maybe could be a freeze plug, or maybe a warped head/leaking HG to the outside? I never had it overheated but it ran on very little coolant a couple of months ago.
There's no pressure in the cooling system, no gooey stuff, just nice and pink coolant.
It always liked a good taste of coolant though (about 1L every 2000kms), but I always thought it to be a small leak somewhere.
I know it's really hard to tell whats going on based on the story, but maybe someone dealt with this one before.
